Definitions
- such an installation comprises an X-ray source 1 sending to a patient 3 an X-ray beam.
- a diaphragm or collimator 5 makes it possible to define the beam of X-rays arriving on the patient at a corresponding zone. to an organ 7 that we want to irradiate.
- Such irradiation facilities are prone to failures that can have dramatic consequences on the treatment of a patient. Or the doses applied are insufficient and the treatment is inoperative. Or the irradiation density provided by error in other organs can lead to their radio-sensitization, which can induce delayed-onset cancer.
- Another solution is to combine the two previous solutions. We then obtain a system that combines the advantages, but also the disadvantages, of multiplexing and individual connections.
- the intermediate zone contains cells having an area of four times the area of the cells of the central zone and the peripheral zone. contains cells having an area nine times the area of the cells of the central area.
- Figure 5 previously described, is a top view of the bottom plate of a few adjacent cells of a matrix X-ray detector
